Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The description lists triggers such as "绑定带宽", "bandwidth config", and especially the bare acronym "GCB", which are broad terms that can appear in ordinary cloud-support conversations outside the narrow intent of this skill. The file does not provide negative examples or clear activation boundaries to distinguish when the skill should activate versus when a more general networking or Cloud Connect skill should be used.
